SPECIFICATION forming art of Letters Patent No. 350,831, dated October12. 1886.

. Application filed July 19, 1886. Serial No. 208,493. (No modeLl To allwhom it may concern:

Be it known that I, DAVID LUBIN, of Sacramento, Sacramento county, Stateof Cali: fornia, have invented an Improvement in Clod Choppers andPulverizers; and I hereby declare the following to be a full, clear, andexact description of the same.

My invention relates to that class of agricultural implements used forthe cultivation of the soil and known under various names-as barrows,Cultivators, 85c; and my invention relates particularly to a machinewhich, from the nature of its operation and the results accomplished,may be termedv a clod chopper and pulverizer.

My invention consists, essentially, in blades or teeth of any suitablecharacter carried by arms, frames, bars, or links, and a mechanismoperated by the progression of the machine for elevating and droppingthe tooth=carrying devices so that teeth will strike and chop the clods,and by this movenientand by the general progression of the machine havea tendency to pulverize them, all of which, together with details ofconstruction, lshall hereinafter fully describe.

The object of my invention is to provide a simple, practical, andeffective machine for this purpose.

Referring to the accompanying drawings for a more complete explanationof my invention, Figure I is a plan of my rlod chopper and pulverizer.Fig. 2 is a side elevation of same. Fig. 3 is a modification showingblades f instead of harrow frame and teeth. Fig. 4. is a modificationshowing the cams traveling on the ground as wheels. Fig. 5is a detail ofthe feathered pinion l.

A is the main frame of the machine, having a tongue or pole, B. The rameis mounted on a fixed axle, O. on the ends of which are looselyjournaled the wheels I).

E are arms, bars, or links located in parallel planes, and in a seriestransversely of the main frame, their upper ends being pivoted to saidframe and to the axle thereof, as shown at e. To'the lower ends of thesearms, bars, or links maybe attached any suitable blades or teeth, orsuit-able frames carrying said blades or teeth. In Figs. 1, 2 I haveshown small barrow-frames F, pivoted to the lower ends of the parallelarms, bars, or links E, said frames carrying the ordinary harrow-teeth,f. In

Fig. 3 I have shown chopping-blades f, Se-

cured directly to the lower ends of the arms, 0

drop again. Various means maybe employed for accomplishing this result,though I prefer to use the cams G, such as l have here shown.

These cams are secured to a shaft, 9, which is mounted on the rear ofthe main frame A, and each consists of two arms separated by one hundredand eighty degrees. the series of cams being arranged in a spiral manneraround the shaft, or in any way in which their operation shall bealternate, successive, or simultaneous in Whole or in part, as may bedesired.

Attached to the frames F are links H, which 1 extend upwardly and areprovided with small studs or pins 11, under which the cams G act, and bytheirimpingement raise said links, thus raising the tooth carryingframes F. A rotary motion is imparted to the cam-shaft g by means ofpinions I upon each end ofsaid shaft, which mesh with annular gears J',secured to the inner surface of the main driving-wheels D of themachine.

The 0 )eration of the machine as far as de- 1 scribed, is as follows:The rotation of the camshaft, which is derived from the progression ofthe machine, causes, through the links H, the elevation of thetooth-carrying frames F, and their subsequent drop when relieved of thecams, said frames moving perfectly parallel on account of the attachmentof the parallel bars, arms, or links F. In thus dropping the toothedframes strike and chop the clods, and as they are advancing at the sametime with the whole machine the tendency is to pnlverizc the clods sochopped. This operation of the toothed frame is a continuous one,because of the successive dropping of the frames or the simultaneousoperation of several, as the case may be. Their motion is also rapid, onaccount of the small pinions mesh ing with the large gears of the mainw'heels. When about to make a turn, or when proceed.

' the cam-shaftgin bearings, adapting it to slide longitudinally. One ofthe'pinions I is keyedthis purpose Ihave the following mechanism.

ing to or from work, it is necessary that the teeth of the machine beraised above the ground and suspended in'that position. For

Pivoted at the rear of the frame are arms N, the upper ends of whichcarry a transverse .shaft, j, on which arelsuspendedfgravitatingpassing, and the hooks fall forward again un ghooks 1''. This shaft isconnected by a rod, is, with a lever, K, within convenient reach ofthedriver. When theleverispushed forward, the shaft j'is'vbrought tosuch a position-that its gravitating hooks j hang directly in the pathof the-uprising pins h of the links'H, attached to the tooth-carryingframes, so, that said pins, coming in contact with the beveled lowerends of the hooks, move them back while der the pins, thus suspendingthe'links H and the tooth-carrying frames. To relieve them again, thelever K has but to be pulled back,

- thereby releasing the'ho'oks from the pins h,

' andallowing the tooth-carrying frames to drop v to pe'sit'ion. It 'isalso necessary at times to relieve the'toothed frames or bars from theaction of the cam-shaft. For this purpose I mount rigidly to said shaft,while the other, as shown onthe left, is-on a spline or feather,- Fig.5.

Each of said pinions is provided with a clutchseat, Z,'with which apivoted clutch-lever, L,

engages; :The levers are connected by rods l with a pivotedoperatingdever, M, at points on each side of the pivotal'center'of saidop-' erating-lever. The movement of this lever M throws the feathered.pinion on the one side' into and out of gear with the gear -.I of themain wheel, and on the other side moves the cam-shalt itselflongitudinally, so as to carry the pinion on that side into or out ofgear with the wheel, and this longitudinal movement of I CGPY 350,831

the cams G upon the upper ends of the pivoted arms, and that the rapidelevation and relief of the two arms of the one pair is effected.

Although I have shown the rotation of the cam-shaft as being effected bypower derived from the wheels of the machine, I may otherwise derive,its rotation from the progression of the machine, as by making the camsthemselves travel onthe ground, andthns act not only to rotate theshaft, but also as wheels for the machine, Fig. 4.

I Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is. v i
